WebbAs much as the correlation coefficient is closer to +1 or -1, it indicates positive (+1) or negative (-1) correlation between the arrays. Positive correlation means that if the values in one array are increasing, the values in the other array increase as well. A correlation coefficient that is closer to 0, indicates no or weak correlation. Webb2 apr. 2024 · The p-value is calculated using a t -distribution with n − 2 degrees of freedom.
